Product details

12 MHz MEMS XO with CMOS output — fit for automotive clock trees

The DSC1001BC2-012.0000 is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a 12 MHz CMOS output with ±25 ppm frequency stability across its 0°C to 70°C operating range. The 4-SMD no-lead package (5.00 mm × 3.20 mm, 0.90 mm seated height) fits a standard 7050 footprint, and the 1.8V–3.3V supply range lets it work across multiple voltage domains without a level translator on the output.

Standby function and supply current — power budget for battery-backed systems

At 6.3 mA max supply current during active operation, the power dissipation in the 4-SMD package stays under 21 mW at 3.3 V — no thermal derating concern for a standard PCB layout.

Frequently asked questions

Does DSC1001BC2-012.0000 meet AEC-Q100?

Yes — the part carries AEC-Q100 ratings, qualifying it for automotive-grade applications such as engine control modules, body controllers, or infotainment systems that require the extended reliability and temperature cycling tests of the AEC-Q100 standard.

Can DSC1001BC2-012.0000 replace a crystal oscillator?

The DSC1001BC2-012.0000 is a MEMS-based XO (Standard) with CMOS output — it replaces a quartz crystal plus oscillator circuit in a single package. Because it includes the MEMS resonator and driver on-chip, you eliminate the external load capacitors and feedback resistor needed for a bare crystal. The 12 MHz CMOS output directly drives a logic input without additional conditioning.
